A good wiper must have characteristics such as heat resistance, cold resistance, acid and alkali resistance, corrosion resistance, ability to fit windshields, low noise, strong water repellency, and soft and scratch-free windshield. How to maintain the car wiper in winter is a key issue. In order to ensure a good view, the wipers usually need to be replaced once a year or so. We can pull up the wiper while maintaining the car wiper, and use your fingers to touch the cleaned wiper rubber to check for damage and how elastic the rubber blade is. If the blade is aged, hardened, and cracks appear, the wiper blade needs to be replaced.
First, confirm that the wiper connection method and specification rods are connected to the wiper rocker arm, and some of the support arms are fixed to the rocker arm with screws, and some are locked with a male buckle. The type of wiper used in vehicles can refer to the manual of the vehicle.
2. Whether the wiper rubber strip is aging or not, pull the wiper up and touch it with a finger on the cleaned rubber wiper strip. If the blade is aged, hardened, and cracked, the wiper is unqualified.
3. Whether the wiper maintains a certain speed at different speeds Place the wiper switch at various speed positions, especially if the wiper maintains a certain speed under intermittent operation.
Fourth, check the state of the wiper If the rubber contact surface and the glass surface can not completely fit, resulting in wiping residue, this wiper is not qualified.
Fifth, the motor with or without abnormal noise If the wiper motor "buzzes" and does not rotate, indicating that the wiper mechanical transmission parts have rusted or stuck place, then the wiper switch should be immediately closed to prevent burning the motor.
How to extend the life of the wiper?
In fact, wipers are not very expensive, but if you can increase the car's own wiper life is not better? Now editors teach you ways to extend wiper life. First, prepare a relatively large water sandpaper, then remove the wiper from the car and put it into the water first, and put the sandpaper together. After a minute, remove the wiper and sandpaper and use the sandpaper to wipe the wiper. Five or so, and then gently rinse with water, put back to the car, test to see if it can not be clean, if not in accordance with the previous method to come back from time to time, this way in turn, knowing that up to their own standards so far. This is because the wiper can already be uneven, smooth and smooth, so as to extend the life of the wiper.
Note: The wiper is not as long as possible. Some people think that the longer the wiper blade, the larger the scraped area and the better the visibility. In fact, although increasing the length of the wiper blade can increase the visible range of the visual field, it will also increase the burden on the wiper motor and the wiper rod. If it is necessary to increase the length, it must be ensured that the wiper operation cannot be interrupted.
